Same here. No amount of changing settings, firewalls, router settings or ports has fixed this for me.
I'm having a similar issue. Re-linked accounts, not getting drops to show up in twitch or Warframe. Nothing in inventory in either place. No messages, pop-ups or anything during streams. I've watched every day this week and have missed all the drops due to this. Campaign is listed in twitch and connection in twitch is listed fine.
